Help with mobile character animations

hello all, I'm new in Unity. I have a character which controls by two joysticks. My character model has no his own animation and I put him animation from another model. Mecanim, humanoid etc. First default "Idle" animation works fine but I can't animate walk animation. it's moves and animates if I press W,S,A and D buttons. if I test it in my iPhone the character model only moves not animates. I have used this script: using UnityEngine; using System.Collections;

public class PlayerMovevment : MonoBehaviour {

 // This component is only enabled for "my player" (i.e. the character belonging to the local client machine).

 // Remote players figures will be moved by a NetworkCharacter, which is also responsible for sending "my player's"
 // location to other computers.
 
 public float speed = 10f;        // The speed at which I run
 public float jumpSpeed = 6f;    // How much power we put into our jump. Change this to jump higher.
 
 // Booking variables
 Vector3 direction = Vector3.zero;    // forward/back & left/right
 float   verticalVelocity = 0;        // up/down
 
 CharacterController cc;
 Animator anim;
 
 // Use this for initialization
 void Start () {
     cc = GetComponent<CharacterController>();
     anim = GetComponent<Animator>();
 }
 
 // Update is called once per frame
 void Update () {
     
     // WASD forward/back & left/right movement is stored in "direction"
     direction = transform.rotation * new Vector3( Input.GetAxis("Horizontal") , 0, Input.GetAxis("Vertical") );
     
     // This ensures that we don't move faster going diagonally
     if(direction.magnitude > 1f) {
         direction = direction.normalized;
     }
     
     // Set our animation "Speed" parameter. This will move us from "idle" to "run" animations,
     // but we could also use this to blend between "walk" and "run" as well.
     anim.SetFloat("Speed", direction.magnitude);
     
     // If we're on the ground and the player wants to jump, set
     // verticalVelocity to a positive number.
     // If you want double-jumping, you'll want some extra code
     // here instead of just checking "cc.isGrounded".
     if(cc.isGrounded && Input.GetButton("Jump")) {
         verticalVelocity = jumpSpeed;
     }
 }
 
 // FixedUpdate is called once per physics loop
 // Do all MOVEMENT and other physics stuff here.
 void FixedUpdate () {
     
     // "direction" is the desired movement direction, based on our player's input
     Vector3 dist = direction * speed * Time.deltaTime;
     
     if(cc.isGrounded && verticalVelocity < 0) {
         // We are currently on the ground and vertical velocity is
         // not positive (i.e. we are not starting a jump).
         
         // Ensure that we aren't playing the jumping animation
         anim.SetBool("Jumping", false);
         
         // Set our vertical velocity to *almost* zero. This ensures that:
         //   a) We don't start falling at warp speed if we fall off a cliff (by being close to zero)
         //   b) cc.isGrounded returns true every frame (by still being slightly negative, as opposed to zero)
         verticalVelocity = Physics.gravity.y * Time.deltaTime;
     }
     else {
         // We are either not grounded, or we have a positive verticalVelocity (i.e. we ARE starting a jump)
         
         // To make sure we don't go into the jump animation while walking down a slope, make sure that
         // verticalVelocity is above some arbitrary threshold before triggering the animation.
         // 75% of "jumpSpeed" seems like a good safe number, but could be a standalone public variable too.
         //
         // Another option would be to do a raycast down and start the jump/fall animation whenever we were
         // more than ___ distance above the ground.
         if(Mathf.Abs(verticalVelocity) > jumpSpeed*0.75f) {
             anim.SetBool("Jumping", true);
         }
         
         // Apply gravity.
         verticalVelocity += Physics.gravity.y * Time.deltaTime;
     }
     
     // Add our verticalVelocity to our actual movement for this frame
     dist.y = verticalVelocity * Time.deltaTime;
     
     // Apply the movement to our character controller (which handles collisions for us)
     cc.Move( dist );
 }

}

How to animate character with joysticks? Thank you in advance))
